Problems solved by technology
Restricted by the conditions stipulated in the standard method, the direct detection of single protective airtight doors (including airtight doors) can only be carried out in laboratories or protective equipment production workshops in China at present, and cannot be realized on the engineering site, resulting in the current domestic protective equipment. After installation, the airtight performance test cannot be implemented, leaving a huge hidden danger to the overall protection performance of the project

Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing.
[0014] like figure 1 As shown, a method for testing the airtight performance of a single protective airtight door is to use film 1 and film 2 to seal both sides of the protective airtight door frame to form an overpressure chamber, and confirm that the air leakage in the overpressure chamber is less than 0.001m 3 After / h, the airtight performance test can be carried out.
[0015] like figure 2 After the reserved opening on the film 2 is opened as shown, the sealing performance of the protective airtight door is tested.

The invention relates to a sealing performance detection method for a single-frame protection air-tight door. According to the method, two layers of films which are made of a PE material are used to form an air-tight overpressure chamber; after the air leakage amount of the air-tight overpressure chamber is measured and confirmed, a reserved opening in the film 2 is opened, process operation to test the air leakage amount is performed. With the detection method adopted, the efficiency of detecting the sealing performance of the protection air-tight closed door can be improved, and the difficulty that the airtightness detection of the air-tight door cannot be performed at an engineering site at present can be eliminated. The method can be widely applied to the independent and rapid detection of the airtight performance of protective devices.
Description
technical field [0001] The invention relates to a method for detecting the airtight performance of a single protective airtight door, which is a method for directly measuring the airtight performance detection after installation on the engineering site, and belongs to the technical field of protection engineering detection. Background technique [0002] Protective equipment is installed at the entrance and exit of protective engineering personnel, equipment, weapon perforation and air intake, and smoke exhaust pipe (pit) crossings. It is used to block shock waves, biochemical agents or weaken shock waves. Airtight performance is its key quality control item. Protective airtight doors (including airtight doors) are an important protective equipment, and there has been no direct measurement method for the airtight performance test after installation on the engineering site. [0003] In addition, there are two commonly used airtight performance testing methods for protective eq...
